Description of problem:
When changing justification of an image (so that it is aligned on the opposite
margin), the picture disappears from the screen.

Version-Release number of selected component (if applicable):
abiword-2.4.6-1.fc6

How reproducible:
Everytime

Steps to Reproduce:
1. Open a file with an image
2. Click on the line with the image
3. Click to change the justification (right, left, or center)
  
Actual results:
The image disappears

Expected results:
The image moves to the opposite margin

Additional info:
The image is still there.  It still is taking up space on the page.  Pressing
print preview will display it.

Clicking on another line and changing its justification will have the added
effect of making the image reappear.  This makes me think it's a missing call to
a function that rerenders the image/page.
